Does a statistics course improve a student's mathematics skills, as measured by a national test? Suppose a random sample of 13 students takes the same national mathematics examination just prior to enrolling in a statistics course and just after completing the course.

Listed are the students' quantitative scores from both examinations. Use a = .01 to determine whether the scores after the statistics course are significantly higher than the scoresbefore.
